Pipe/tube conveyors a modern method of coal and ash transportation
For more than 100 years the troughed belt conveyor has been used to transport bulk materials. Its success has been attributed to its relatively low capital cost, high degree of reliability and availability, and low operating and maintenance costs. The only significant problems with conventional conveyors have occurred at transfer points when the transported materials were sticky, dusty or there was a need to provide a totally enclosed system to protect the product from the environment or contain dribble from the return belt. The pipe or tube conveyor solves these problems by transporting the product in a circular cross section formed by overlapping the belt edges and using idlers arranged in a hexagonal pattern to form a tubular shape. The belt encloses the product being conveyed and protects the product from the elements and the environment from the product. The return belt is also formed into a circular cross section, rolled with the carrying side of the belt inward to prevent material clinging to the belt from dislodging at the return idlers.
